Hello,

Generally, you don't have to power-off any switch, while replacing stack cable.

I am not sure about the complete stack cable connections.

Please send "sh switch neighbor" with "sh ver | inc IOS"

Hello,

I guess you are trying to replace the stack cable connected between Sw1-SP2<<==>>Sw4-SP1. If so, it shouldn't be a problem.

Did you notice the stack cable connection between Sw3-SP1 <<===> Sw4-SP2 ?

From the command results, I see Sw4 has no stack neighbors.

Hello,

I am not aware of any document that provides the details you requested.

Managing Switch Stacks - doc on CCO:

Shouldn't be a problem just pulling one cable , the ring will wrap and run at half bandwidth I believe  until the cable is replaced.
